Abstract Finding the shortest travelling distance based on various situations might assist travelers in making a better selection of route decisions. The main goal this paper is to solve routing problem for company’s fleet vehicle (XpressBees) order find best under constraints such as Signalized Intersections, Vehicle Capacity, Customer Demands, and Time Windows reduce transportation costs by u...

AbstractThe statistical models supporting the Highway Safety Manual quantify associations between aggregate traffic measures, such as average daily volume or posted speed limit, and crash f...

Micro-simulation models are rapidly gaining acceptance as promising tools to analyse and evaluate ITS and other traffic control and management measures. Capacity is a primary concept in most of traffic engineering studies, however micro-simulation models generally ignore this concept. There are significant numbers of studies on capacity analysis based on analytical approaches including Highway ...

1 2 Transportation planning has been playing a critical role in shaping the economic health and 3 quality of life. It not only provides insight into the mobility of people and goods, but also 4 influences patterns of growth and economic activity. Metropolitan transportation planning is a 5 challenging transportation topic due to the lack of future traffic information, such as evaluation 6 of th...

Introduction Congestion bottlenecks are severe traffic chokepoints where demand far exceeds available highway capacity. The Federal Highway Administration (FHWA) of the US Department of Transportation states that recurring bottlenecks account for the largest share of road delay in the United States (40%), far exceeding traffic incidents (25%), inclement weather (15%), construction (10%) or othe...

The manual handling of concrete highway kerbs remains commonplace in the construction industry despite obvious risks to operatives. This study was undertaken to find out why kerb installation still includes manual handling, to identify the alternatives that exist and to consider how the organisation of the work affects exposure to risk. Focus groups were held with industry professionals to disc...

BACKGROUND Intersections generally are analyzed (using methods such as CLV and HCM) as part of a TIS in order to determine if there is adequate residual capacity available in order to add additional traffic through an intersection as a result of proposed development. If the analysis indicates that adequate residual capacity does not exist, additional analyses are performed under various improve...

By introducing the speed-elasticity of flow, this paper provides a generic characterization for equilibrium speed-flow curves that satisfy the fundamental identity of the traffic flow. With this new characterization, we have integrated several well-known speed-flow models, including the classic Greenshield-type and Underwood-type models, and the most recent specifications for highways from High...
